Prologue^^

Omega's POV

I was in the market place on a planet called Tyrant. I have been on this planet for about a month now. This planet was currently under martial law. The ruler being a man named Mylous Ferrer. Mylous was a cruel man who cared only about himself. He has committed a countless number of crimes. Ranging from pick pocketing to murder, genocide, massacre, you name it, he's done it. He was power hungry and deserved to die. That is exactly what I was here for.

"Hey Alpha, Alpha?" the voice of Sophia snapped me out of me thoughts. Sophia was a blonde haired 10 year old girl with light blue eyes that I found adorable. "Hmm." I answered confused. "I said, that we better hurry, my daddy will be setting off on his hunt soon and he might notice that I'm not at home when he tells me to get something for him. And I also asked when you were gonna, you know." At this, she drew a finger across her neck, "kill him." "Shush. Sophia, how many time have I told you not to say that in public, let alone the black market. You never know who could be watching or listening in on us at this very moment." I said in a hushed but stern manner. "Oh yeah. Sorry." she whispered. I rubbed her head affectionately and continued walking down the crowded streets of the black market.

Did I mention that Sophia's full name was Sophia Ferrer? Meaning that she was related to Mylous? In fact, she was Mylous' youngest daughter. So why would a girl of 10 years be so comfortable with a man killing his father? There are several reasons. First is that, virtually every sane person on this planet hates Mylous, including his family. But very few on the planet even knew that Mylous has a family. He liked to keep it a secret because he saw his family as a weakness that his enemies could exploit. Not that he cared, but it would make him look bad infront of the people if he did not rescue his family. And if he were to rescue them, it would cost him a considerable amount of money or power. And he couldn't have that, could he? Besides if he didn't save his family, it might fuel the revolution.

Second, Sophia was very mature for her tender age. Too mature if you asked me. Sophia didn't even have a chamce at childhood because of her father. But I'm gonna change that.

Today is the day that I have set for Mylous' end. It was pretty simple really. On the first day of every month, Mylous would set out on a hunt and kill the largest beast he could find in the forest. He would bring it back and show the people just how strong he was to discourage anyone who dares defy him.

The thing that the people didn't know is that Mylous is a lazy, decieving asshole that makes other people do the work for him and takes all the credit. The person who happens to do it for him was, Henry, his first born son. He couldn't careless if Henry got hurt. He'd just say that it was a freak accident that he couldn't prevent.

Usually, Mylous will go in the part of the forest which is deep enough so that the people won't see him but not too deep where all the dangerous monsters are. This is perfect for me. He would be all alone and people probably won't hear him when he is begging for mercy. Anyway, I would get the mission overwith the people get a new new leader which will hopefully be someone who doesn' t let all the power get into their head. A happy ending for everyone, except Mylous.

"Today actually. Right when he is "out hunting". And your right, we should be heading back." I answered Sophia's previous question. "Cool."

I sent her back to her father's mansion, while I headed for my tent. On the out side it didn't look like much. A regular black tent in the forest. On the inside, it was enchanted to be the size of a small appartment on earth. It had living room space, a small kitchen area and a corner for me to sleep in.

I went in side and put on my assasin outfit. It looked sort of like a ninja's clothes. All black, a belt around my waste for all my throwing knives and a few daggers. It didn't take long to put it on because I have been so used to doing this.

After I was comfortable with the way I wore the clothes, I headed out. I leasurly walked towards Mylous' mansion which wasn't too far from my tent. It was a nice sunny afternoon, a good day for a stroll in the woods, have a day at the beach and assasinate the most feared man on the planet. A normal day for me.

When I got there, I could hear Mylous noisily making his way towards the forest with a crowd cheering him on. The people only did this because if they didn't, then it could mean certain death.

Anyway, I followed Mylous and Henry into the forest keeping to the shadows, making sure that Mylous did not know of my presence. I told Henry the plan earlier on that week. It was a simple one that even an idiot could think of. Henry leaves his father to supposedly kill a large beast. I would talk to and then kill Mylous. I would get Henry and he would make up a story of how his father died and I would go home never to return unless I was needed. Then we would all go on with our lives. The end.

When Henry was far away enough, I threw a silver knife at the tree that was inches away from Mylous. But he still had a small scratch on his cheek that I had hit with knife. The knife landed into the tree trunk with a satisfying thump.

Mylous shot up from the rock that he was sitting on and looked around wildly in all directions. His eyes full of fear. I held back a chuckle. I made some noise when I jumped from tree to tree. Usually, assasins would just kill their target to get the job over and done with. But I liked to get my targets talking.

So in my deepest most menacing voice, I said, "Consider yourself lucky Mylous" At this, he looked towards my direction. I jumped from one tree to another each time throwing a knife that would leave a small scratch on his face. He now had a total of 3 scratches.

"Wh-who are you?" He stuttered. Looking at the last place where my last knife had hit him. "I go by many names. But to you, I am Omega, the last and final thing that you will live to see." I said. I landed softly on the ground and was currently a good 8 feet away from him but not before throwing a final knife at him. A total of 4 scratches on his face.

He was now shaking with fear, literally. "W- why are you after me? I-i have not done you any wrong. Spare me and all your wishes and desires will be realised. I am a very powerful man. I could give you what your heart desires most. Name the price of the person who sent you. I will double, no triple it." He said, his confidence was slowly coming back.

Thud. Thud. That was the sound of two more knives that connecting with tree bark after it hit Mylous' skin. A total of 6 scratches."You may have not done me wrong. But how about the people you have tortured just to gain the power you have? How about the women and children that have been left to fend on their own because you killed their father, brothers or sons? Have you ever thought about them?" I said in a tone full of anger and malice.

"I-I have a family too, you know. What will happen to them if you kill me? I have a son, 3 daughters and a wife. How will they survive if you kill me?" He stamerred, the earlier confidence in his voice gone.

"Your son is a warrior, a good leader. He is skillful and brave, it won't be impossible for him to get into the army. Your eldest daughter is a capable young woman. She is intelligent and can fend for herself.

Your second daughter is head strong and not afraid to speak her mind. Your youngest daughter is kind and despite her young age, is very mature and can put up a fight. Your children have the qualities to make a good name for themselves in society. I won't be surprised if they are the ones who will lead the people when they slowly recover from your rule. As for your wife, although she is old, she is more then capable of defending herself. If you spent time with them instead of ending innocent lives then maybe you'll know these things about them too. I told you before that I go by many names, to your family and to the people you tortured, I am known as Alfa. I will signify the beginning of their new lives. A chance to start over and begin anew and forget the past. They will be happy that you are gone from their lives. And as for my price, it would be the end of your life by my blade. Any last words?" I said nochalantly. Slowly advancing towards him while he backed away.

"I do not regret anything that I have done. I will go down in history. They will sing songs about me and speak of legends about my greatness. While they curse you as a mindless assasin who is only capable of following orders and not able to think for yourself. You will be known as the one who killed an innocent man. You will be portrayed as a heartless maniac who only knows how to kill and lives for that purpose." His voice full of pride and dignity. He could no longer back away as there was a tree in the way.

"Are you done? Funny... Seems like you just described yourself on the latter part. Once a fool always a fool. I was hoping that in the face of death, you'd confess your sins and feel at least a hint of remorse. If you did that, I could have put in a good word for you when you enter the void. Don't get me wrong you will still be punished and receive pain that you would have never thought possible. But your confession would have decreased your punishment, not by much but where your going, that little amount of deduction in your punishment would feel like a gods send. But sadly you did not. So good bye Mylous Ferrer."I was still advancing toward him at a steady pace.

I drew one of my daggers. This a special dagger that was able to produce any kind of poison that I could think of. I chose for him to die this way because, I was trying to go for the 'natural look' kind of death. So that people won't suspect Henry. Since Henry was the one who will "stumble upon" Mylous.

This particular poison belongs to one of the more common but deadly snakes found in this forest. The poison does not instantly kill its victim. Instead, the venom first causes the victim to have hallucination. Then it will cause the victim to experience all the pain he has suffered through in life. After all the torture, once the poison has made it through the person's heart, it will still take about half an hour for the person to die. But this depends on how much poison is injected into the body. Unlike most poisons, where the more poison in you the faster you are killed. This is the complete opposite where the more venom injected in your bloodstream, the longer it takes for you to die. I was now only inches away from Mylous. I grabbed his shaking arm and made a pattern that looks like the snake's teeth.

By my calculations, it would take at least 5 hours for Mylous to die. So I gagged him, tied him securely around the trunk of the tree and looked around for Henry.

I found him a distance away. I told him what happened. Said my good byes and told him to take good care of his family. With that, I vanished. I would probably visit Henry in the future but he won't see me.

I always decide on how to kill a person by the way they act when on the verge of their lives. Mylous was a stuborn one. If had admitted that he had done wrong then I would have permitted a quick and painless death. Sort of like the calm before the storm. Because where these people are going, it's gonna be one hell of a storm, literally.

The people who I kill go to place known as the void. Back on earth it has a counterpart known as the Underworld. The Void has four levels. The best being Refuge, a.k.a elysium. But Refuge is 10 times better. The next being Estancado a.k.a asphodel. The third is Castigo a.k.a the fields of punishment. The last level is saved for the worst of the worst. It is meant for people like Mylous. It is ten times worst than tartarous belive me, I should know I've been to both. It is known as Eterno.

Now you might be thinking, who does this guy think he is? Why does he go around judging people who kill others, when his proffesion in life is an assasin? Who is this hypocrite that should deserve Eterno as much as Mylous does?

I go by many names as I have told Mylous. I am known as Alfa as well as Omega. I personally prefer Omega, it sounds cooler. I am Omega, son of none, commander of the Chaotic army, one of the most powerful armies the universes has ever seen, Chaos' personal assasin, his apprentice, right hand man, his wing man, second only to Chaos in the whole universes in terms of raw and pure power, blah, blah, blah... My title could go on and on, but it would take too long, I don't want to bore you and besides, even I can't remember all the things I've done.

But before I was Omega, I was known by another name. My name was Percy Jackson, son of Posiedon, Saviour of Olympus, Prince of Atlantis, Lightning thief, Bane of Kronos, Bane of Gaea, yet another name that has so many titles that get jumbled up in my head. But there is one title that goes along with that title that I can never forget.

And that is, Percy Jackson, Betrayer of Olympus.

That was the prologue. I hope you enjoyed reading it as much as I had fun writing it. Till next time.
